ABSTRACT:
A seismic data collection unit having multiple separate geophones/geophone packages positioned in a housing wherein the geophones are offset from a vertical axis so that summing of the geophones' respective outputs minimizes certain noise in the unit's output. Specifically, the offset geophones are physically positioned or mathematically configured so as to be symmetrical about a selected vertical axis in order to cancel out certain noise in a seismic signal. The particular placement of the geophones within the housing is preferably selected so that the vertical axis around which the geophones are positioned passes through the center of gravity of the unit.
